Effects of the fresh and dried housefly (Musca domestica) larvae in the diets of Nile tilapia Oreochromis niloticus (Linnaeus, 1758): growth, feed utilization efficiency, body composition and biological indices
A 56-day feeding trial was undertaken to assess the ef-fects of housefly maggots (HM) forms (dried and fresh) as protein sources on growth, feed efficiency, and body indices of Oreo-chromis niloticus finger-lings. A control diet (T0) contained 300 g/kg of fish-meal (without HM). Two practical diets with the same formula were prepared with dried HM (T1) and fresh HM (T2) where 66 % of the fishmeal was replaced. Di-ets were fed to triplicate groups of tilapia (mean ini-tial weight: 10.26 ±0.12 g). There was no difference in survival, condition factor, feed conversion ratio, and protein efficiency ratio. Fish fed diets T0 and T1 had sig-nificantly increased (P < 0.05) mean final weight (50.25 ±1.39 - 52.24 ±1.03 g), specific growth rate (2.84 ±0.03 - 2.88 ±0.03 %/day) and weight gain (389.70 ±7.63 - 402.78 ±8.16 %) compared to T2 diet ones (46.30 ±2.03 g; 2.67 ±0.07 %/day and 356.70 ±7.76 % respective-ly). Viscerosomatic and hepatosomatic index in fish fed T1 and T2 diets were significantly higher than those fed T0. The present findings indicate that the dried form of housefly maggot has given the best results in terms of growth compared to the live form. However, housefly forms did not affect feed efficien-cy parameters.
期刊介绍:
The journal (IAR) is an international journal that publishes original research articles, short communications, and review articles in a broad range of areas relevant to all aspects of aquatic sciences (freshwater and marine). The Journal specifically strives to increase the knowledge of most aspects of applied researches in both cultivated and wild aquatic animals in the world. The journal is fully sponsored, which means it is free of charge for authors. The journal operates a single-blind peer review process. The main research areas in aquatic sciences include: -Aquaculture- Ecology- Food science and technology- Molecular biology- Nutrition- Physiology- Water quality- Climate Change
